Abstract: 1800. Boult, A. J., [Stern. A.]. Jan. 22. Cigarette-making machines.-The machine comprises mechanism for rolling up the paper tube, transporting it to the tobacco-filling device, which may be of well-known construction, and rolling up and inserting in the end of the cigarette a paper mouthpiece. Fig. 2 shows a plan view of the machine. The paper for the wrapper is fed forward by the intermittent motion of a rubber-surfaced wheel 3 co-acting with pressure rolls 1 and 2. It passes first between guide-plates 10, and as each length is cut off by the knife 13 it is gripped between a pair of fingers 12 carried by a frame 11 arranged to traverse on a fixed guide 21. One edge of the paper is first approached to the gumming-roller 30, and pressed upon it by the depression of a thin metal plate 33 pivoted at 31. The fingers 12 then carry the paper to the mandrel on which it is to be rolled up into a tube. The rear end 37 of the mandrel is seen in the Figure. A bar is arranged to clamp the paper to the mandrel in the act of rolling, and a spring plate 51 closes the gummed seam at the last part of the revolution. The mandrel is advanced for the delivery of the finished tube by the action of a cam 61 on a friction roller mounted on the lever 63, which is connected by a ball-and-socket joint 64 to the end of the mandrel. The transporting-device for the tube is shown in side elevation in Fig. 8. It serves to carry the tube first to the tobacco-filling device and then to the point where the mouthpiece is placed in position. It consists of pivoted jaws 79 opened and closed by a looselymounted fork 81 operated by the cam 90 and linked rods 87, 83. The arm 75 which supports the jaws rocks on the pin 74 under control of the cam 76, and a to-and-fro movement of the whole device is effected by the cam 67, two-armed lever 70, and sliding piece 72 in which the pin 74 is fixed. The mandrel having advanced towards the transporting-device, the jaws of the latter close upon the paper tube and draw it off the mandrel. It is then carried to the tobacco-discharge opening D, Fig. 2, from which tobacco, fed by the belts 129, cut by the knife 132, and pressed by the device 137, is forced into it by the advance of the rod 140. The jaws now carry over the cigarette to the position which they occupy in Fig. 2, in order to receive the mouthpiece. The latter consists of a strip of paper rolled up into a spiral on a mandrel 91 shown in section in Fig. 13. The mandrel has a slot 92 and is surrounded by a sleeve 93 having double slots 94 for the entry of the paper strip. A spring-controlled plate 100 maintains the rolled-up mouthpiece in shape until it is advanced and pushed into the cigarette. The paper strip is carried forward intermittently between a movable guiding and clamping plate 115 and a fixed plate 116. Knives 123, 124 act together to cut out a triangular piece from the strip, the knife 123 thus trimming off square the end of a piece already coiled up on the mandrel, and the knife 124 at the same time cutting the paper obliquely for the next mouthpiece, which is more easily rolled from an obliquelycut end.
